A Marine Protein-based Dietary Supplement for Subclinical Hair Thinning/Loss: Results of a Multisite, Double-blind, Placebo-controlled Clinical Trial.

ABSTRACT: INTRODUCTION:Since skin and hair quality are potent vitality signals, and hair growth deficiency can cause significant psychological morbidity. In addition to clearly-defined hair loss disorders, milder forms of hair thinning or hair loss appear to be increasingly common, with a suggestion that sub-optimal diets and stressful lifestyles may be involved. METHODS:Here we assess the value of a dietary marine-extract based dietary supplement in premenopausal women with subclinical hair thinning or hair loss conditions. This multi-site, randomized double-blind, placebo-controlled clinical trial was conducted with impact on hair shedding rate and hair fiber diameter (assessed by phototrichogram) as primary end points upon consumption of the oral supplement compared to a placebo. A total of 96 eligible female subjects were enrolled aged 21-55 years of age from Asian, Caucasian, and Hispanic ethnic backgrounds. RESULTS:This study showed that hair shedding was significantly reduced in the first 3-6 months of daily consumption of the oral supplement. Moreover, phototrichogram image analysis revealed a statistically significant increase in the mean vellus-like hair diameter after 6 months of supplement consumption, when compared to the mean vellus-like hair diameters measured at baseline. DISCUSSION:These results support the view that a nutritional supplement approach may be useful for women in this age group to deal with subclinical hair thinning or hair loss conditions, and those components of this marine extract-based oral supplement may be a useful adjunct.

Project description:BackgroundThe purpose of this study was to assess the effect of 8-weeks ingestion of a commercialized joint pain dietary supplement (Instaflex™ Joint Support, Direct Digital, Charlotte, NC) compared to placebo on joint pain, stiffness, and function in adults with self-reported joint pain. Instaflex™ is a joint pain supplement containing glucosamine sulfate, methylsufonlylmethane (MSM), white willow bark extract (15% salicin), ginger root concentrate, boswella serrata extract (65% boswellic acid), turmeric root extract, cayenne, and hyaluronic acid.MethodsSubjects included 100 men and women, ages 50-75 years, with a history (>3 months) of joint pain, and were randomized to Instaflex™ or placebo (3 colored gel capsules per day for 8 weeks, double-blind administration). Subjects agreed to avoid the use of non-steroidal anti-inflammatory drugs (NSAID) and all other medications and supplements targeted for joint pain. Primary outcome measures were obtained pre- and post-study and included joint pain severity, stiffness, and function (Western Ontario and McMaster Universities [WOMAC]), and secondary outcome measures included health-related quality of life (Short Form 36 or SF-36), systemic inflammation (serum C-reactive protein and 9 plasma cytokines), and physical function (6-minute walk test). Joint pain symptom severity was assessed bi-weekly using a 12-point Likert visual scale (12-VS).ResultsJoint pain severity was significantly reduced in Instaflex™ compared to placebo (8-week WOMAC, ↓37% versus ↓16%, respectively, interaction effect P = 0.025), with group differences using the 12-VS emerging by week 4 of the study (interaction effect, P = 0.0125). Improvements in ability to perform daily activities and stiffness scores in Instaflex™ compared to placebo were most evident for the 74% of subjects reporting knee pain (8-week WOMAC function score, ↓39% versus ↓14%, respectively, interaction effect P = 0.027; stiffness score, ↓30% versus ↓12%, respectively, interaction effect P = 0.081). Patterns of change in SF-36, systemic inflammation biomarkers, and the 6-minute walk test did not differ significantly between groups during the 8-week studyConclusionsResults from this randomized, double blind, placebo-controlled community trial support the use of the Instaflex™ dietary supplement in alleviating joint pain severity in middle-aged and older adults, with mitigation of difficulty performing daily activities most apparent in subjects with knee pain.
